Power MOSFET tutorial, Part 1

Power MOSFETs are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of ...

Selecting n-channel MOSFETs for High-Side Hot-Swap Control

Find a downloadable version of this story in pdf format at the end of the story. TYPICAL HIGH-SIDE, n-channel, hot-swap “soft-switch” systems use a charge pump to drive the gate of an external MOSFET ...

P-Channel Power MOSFETs Approach N-Channel Performance

The source voltage of a P-channel device is stationary when the device operates as an HS switch. Conversely, the source voltage of an N-channel device used as an HS switch varies between the low side ...

Power MOSFET Tutorial – Part 2

V (BR)DSS (sometimes called BVDSS) is the drain-source voltage at which no more than the specified drain current will flow at the specified temperature and with zero gate-source voltage. This tracks ...
